Yi Chen did not leave the medicine hall, but tossed and turned in the medicine hall for nearly a quarter of an hour, and after going through many investigations again, he arrived at an alchemy room that had just been cleaned.

There are not many furnishings in the alchemy room, only a four-legged bronze pill furnace more than one meter high, and a very simple futon for meditation and recovery.

The reason why he came here was because there was another thing that he needed to do, and this matter was the main purpose for Xiao Qian to ask him to come here, that is, to refine a medicinal liquid that had been researched in recent years-Hanqing liquid.

Hanqing liquid is a first-order medicinal liquid that has only been developed in recent years, and it is also the kind of liquid that Yi Chen took when refining Diyan liquid not long ago, although the level is only at the level of the first order, there are not many people who can refine it in the current Starfall Land.

There are two factors in it, the first is that in the current Starfall Land, although there are extremely many pharmacists who have not yet stepped into the first-order alchemist, there are very few people who have actually become first-order alchemists.

The status of alchemists in the cultivation world is already very noble, let alone in the starfall land after the cataclysm, so these few alchemists have naturally become the most important and saught-after personnel resources.

It can be said unceremoniously that as long as a certain force in Starfall City has any of these alchemists, it can bring unimaginable wealth to this force, and the collection of every kind of cultivation resource is far beyond the imagination of others.

If you can take advantage of such a good opportunity to successfully rise, you will be able to tightly restrain the lifeblood of every cultivator's elixir in the future.

According to Yi Chen's intelligence, there are less than eight alchemists who are still active in the current Starfall Land, and four of them are originally scattered alchemists, who belong to Qingyan Tower and the Invisible Gate that is hostile to it.

However, the remaining four people were actually people from a certain force before the catastrophe, and two of them even reached the level of second-order alchemists.

It's just that they have been sent out to run businesses in other regions before, or they happened to leave Qingyang County, so they were not affected by the catastrophe, even though the forces that could be attached to them had dissipated, but they took over the remnants of the original forces with their own connections.

The small number is enough for them to become the lords of a small force, and the four people who are not willing to be subservient to others have already left here and gone to develop in the rest of the region.

The second is the emergence of the Hanqing liquid pill and the power researched, this liquid is actually under the joint promotion of the two forces, after nearly half a year to research, its purpose is only one, that is, to use it for the collection of Diyan liquid.

Therefore, no matter which reason it is, it is destined that the circulation of cold clear liquid will inevitably be strictly controlled by the two major forces, especially the protective work done on the Danfang, which has been done to the extreme, unless it is a person recognized by the two major forces, there is no possibility of touching it.

Just like Yi Chen, it took nearly three years, going through all kinds of tests from the hall master of the Medicine Hall, and with Xiao Qian's secret help, he was able to get the entire Dan prescription of Han Qingye in his hands a few months ago.

To sum up, the refining of Hanqing liquid is not difficult, it is rare that if the alchemist wants to have a complete Dan Fang, he needs the alchemist to make significant contributions to the two major forces of Qingyan Tower and the Invisible Gate, as well as show enough loyalty, before he can obtain the complete Dan Fang.

The environment of the alchemy room is very clean and refreshing, and the air is also filled with a strong medicinal fragrance, and there are many types, with the attainments of Yichen's first-order alchemist, it is difficult to completely distinguish them for a while.

Yi Chen did not rush to start refining, but began to investigate every place in the alchemy room, until he was sure that his every move would not be known by others, and then he walked to the futon and sat down cross-legged and began to adjust his state.

Alchemy is a very mental and physical process, which requires every point of perception of the alchemist to be extremely concentrated, and it also involves the rapid conversion between many different steps, and the slightest distraction will make the medicinal materials in the Dan furnace completely scrapped, so this step is the choice of every low-level alchemist.

A quarter of an hour later, Yi Chen, who was meditating in meditation, saw a light in his eyes, and his right hand swiped on the storage bag that Xiao Qian gave him, and after three flashes of white light, a snow-white lotus flower equipped with a jade box, ten small blue grasses as high as an adult's forearm, and a jar the size of a human head fell in front of him one by one.

The refining of Hanqing liquid requires the combination of three different main medicines, and then combined with some other common medicinal materials to enhance and fuse, so that it can be refined.

The first of the three main medicines is a cold plant called Ice Lotus, which is what is contained in the jade box in front of Yi Chen's eyes.

This is a kind of snow lotus that grows in cold places all year round to absorb the cold and grow, with three leaves and seven petals, and the whole body presents an almost transparent snow-white color when mature.

Due to absorbing a large amount of cold air in the environment for a long time, every part of the ice lotus is very cold, and when it blooms, it will release a strong and terrifying cold from the flowers, which is enough to completely freeze everything within a hundred meters of the surrounding area in an instant, and it will last for a day.

Such a power is enough to prove the horror of the cold qi inside the ice lotus, even if there is a cultivator in the innate realm who has cultivated in the body, when facing this cold qi, he also needs to use his own body protection true qi to run outside the body, so that he can resist and pick the ice lotus at the same time.

However, although this kind of cold qi is terrifying, it is regarded as a nightmare existence by many mortal realm cultivators, but after being processed by some methods of alchemists, the terrifying cold ability in it will be greatly reduced, which is enough for cultivators to use it, and it can also become a good means of attack after collection.

Especially as an auxiliary medicinal material, when refining inflammatory medicinal materials and treating injuries, it can show a powerful effect that ordinary medicinal materials cannot match.

The second herb is the blue grass in the middle of the three, which is called Qingxin Grass, which is a very common low-level medicinal herb in the cultivation world, and has some effect on allowing practitioners to calm their minds and eliminate the anger in their hearts.

However, the effect of the Pure Heart Grass under fifty years old is not obvious, it is more as a medicinal material for domesticating low-level beasts with milder ferocity, and if it wants to be useful to mortal realm cultivators, it must be at least more than fifty years.

"Hey, is this the third main medicine? Sure enough, it's exactly the same as what the Danfang says, and it's really a peculiar medicinal material."

When Yi Chen's gaze turned to the third main medicine, even he felt a burst of surprise.

The index finger gently scraped a little green liquid from the edge of the altar in front of him, and Yi Chen's eyes that were staring intently bloomed with a very rare light called excitement.

This is the third flavor of the main medicine, according to the Danfang records, it is the juice collected from the root of a vine called iron scales, because this juice is the first time Yi Chen has seen it, as an alchemist, he can't help but feel curious and excited in his heart.

The Iron Scale Vine is a new medicinal herb that was affected by the Cataclysm in the Starfall Land, and was formed from an ordinary vine after undergoing some kind of mutation, and is now unknown to the outside cultivation world.

There is only one place in the Starfall Land, and that is the place where the Diyan Liquid is located that is controlled by the two forces of Qingyan Tower and the Invisible Gate, in a sense, this is actually a medicinal material controlled by only two major forces.

Its surface looks the same as the liquid flowing from ordinary vines, and it does not exude any peculiar fragrance unique to medicinal herbs, it looks very plain, and he has not been able to see anything special with his cultivation in the realm of three pills.

Only when Yi Chen probed his perception into the liquid on his fingertips, a very surprising discovery attracted Yi Chen's attention.

Inside the juice, each drop contained nearly twenty drops, a substance that looked like fish scales but emitted a subtle metallic glow.

Especially when Yi Chen transported the true element in his body and wanted to separate it from the juice, these fish scale substances turned into a small fragment shaped like soft armor the moment they touched the true element, firmly protecting Yi Chen's index finger.

And when Yi Chen's true yuan is dispersed, the juice will change back to its previous appearance again, and the transformation is very magical, even Yi Chen, who has seen such a strange substance for the first time, can't help but play with it, and keeps repeating this process in his hands.

"Huh, this is ......"

However, at the time of the seventh transformation, Yi Chen couldn't help frowning as he looked at the liquid that had slipped from his index finger and had never changed in any way, and his eyes gradually fell into contemplation.

However, although Yi Chen's face was full of doubts, an uncontrollable thought appeared in his mind and gradually occupied his brain, so that the light shining from his eyes became even brighter.
